CONTROLLER PEDAL FOR 'I lIEtiNSLvISSIOIN'S.Y

Application led August 13, 1925, Serial No. 49,923. Renewed August 17,1927. y

The invention relates to pedals designed more particularly forlcontrollingy variable speed and reverse transmission gearing.

One object of the invention is to provide an improved foot-piece for apedal Which may be produced essentially of sheet metal parts which maybe readily assembled so that it may be produced at a low cost.

Another object is to provide an improved lo footpiece which isadjustable in Width so that it may be litted to the sides of the shoe ofthe operator to more effectively control lateral movements of the pedal,desired more particularly in devices in which a singlepedal is used tocontrol the variable speed and reverse transmission gearing.

Other objects Will appear from the detail description.

The invention consists in the several novel features hereinafter setforth and more particularly defined by claims at the conclusion hereof.

ln the drawings: Fig. 1 is a transverse section of a pedal embodying theinvention. Fig. 2 is a section taken on line 2-2 of Fig. 1. Fig. 3 is asection taken on line 3 3 of 'Fig 1. Fig. 4 is a perspective of thesheet metal cover-plate. Fig. 5 is a detail perspective of one of theadjustable side-lugs. Fig. 6 is a perspective of the upper plate.` Fig.7 is a perspective of the bottom-plate. .Fig 8 is a perspective view ofa spacer plate.

The invention is exemplilied as applied to a foot-operable lever D, thelower end of which is usually pivoted so that the upper end isuniversally movable and operable by the foot-piece. The latter comprisesa topplate 10, which is shaped of a flat plate of sheet metal cut andbent to form downturned integral ears 11 which are adapted to straddlethe upper end of the lever D and to be connected thereto by a bolt 12which passes through the lever and through aligned holes 13 in saidears. The downturned ears, cut from the plate, leave transverse slots 14which extend to the sides of the plate 10. A bottom-plate 15, alsoformed of sheet metal, has its margin shaped to conform to the margin ofthe plate 1Q, and is formed With apair of slots 16, the inner ends ofwhich are notched, as at 17, so that the ears 11 may be extendedtherethrough in assembling the foot-piece, and so the bottom plate willbe held and positioned over the top-plate and against longitudinal orlat-eral displacement. .The outer ends of slots 16 are closed.Adjustable side-lugs, also formed of sheet metal, are providedy for thefoot-piece. Each Y' lug compris-es a horizontally extending portion 18which is slidably fitted in one of the slots 14 and rests on theside-portions of the bottom-plate 15, an upturned integral lip or guard19 adapted to engage one side of the op'erators shoe or foot, adownturned ear20,

provided with a hole 21, through Which the bolt 12 passes, and shoulders22 to extend under the underside of bottom-plate 15. These lugs are alsonotched, as at 23, to receive the margins of slot 14 in plate 10, sotheir horizontal portions 18 overlie and rest on the margins of slots'16in the bottom plate. c

Spacer-plates 24 are provided to lvariably space the ears20 of theside-lugs from the ears 11 on the platev l0, to correspondingly adjustthe lugs and so they Willfbe securely held When the bolt 12 istightened. Each spacer is provided With a hole 25, through which thebolt 12 extends, shoulders 26 to f' extend under the bottom-plate 15,and an extension 27, fitting into the slot 16 of plate 15. .Nut 28 onbolt 12is adapted to clamp the ears ou the side-lugs, spacers, ears 11on the intermediate platerlO together, and to hold the bolt in theleverD. i

` A sheet metal cover-plate 30, which is usually utilized to display thename of the manufacturing concern, fits over the top face of plate 10and the portions 18 of the side lugs to hold the lugs on the bottomplate 15, and is provided with a dovvnturned marginal flange 31 fittingaround and 'enc-losing the edges of plates 10 and 15. This plate 30 isalso provided With slots 32 to permit the h lips or guards 19 to beadjusted inwardly or outwardly. The flange 31 extends, as at 33, aroundthe outer ends of these slots 32 to underlie the' portions 18 of theside-lugs so they will hold the cover-plate in connected relation withplate 15, the top-plate 10 being confined between the cover and plate15.

By shifting more or less of the spacers 24 to the outside of the ears 20of either or both of the side-lugs, the distance between them may. bevaried, so that the shoe or foot of tlie individual operator will fitsnugly between the guards 19. If desired, either of the side lugs may beadjusted inwardly or eut-.wardly by corresponding placement of thespaces 24, so that the center of the shoe may be at either side of thecenter of the pedal. The bolt 12 and nut 28 are adapted to clamp theears on the side-lugs and the plate 10 and the spacers securelytogether, to iiXedly hold the footpiece on the pedal. By removing nut 28and withdrawing the bolt 12, the foot-piece may be disconnected from thelever D. The eX- tensions 27 on the spacers, are tapered as at .27, tofacilitate their insertion into place.

Lever D may be provided with an abutment l to it against the undersideof plate 15 to properly angle the foot piece relatively to the lever.

Vhen the bolt has thus been withdrawn from the foot-piece, the shoulders22 and margine of portions 18 of the side-lugs, between which the plate15 is confined, will hold the bottom plate and side-lugs in connectedrelation. The flange-portions 33 ofthe cover plate underliethelug-portions 18, so that the cover-plate will be held in connectedrelation to the side-lugs and the bottom-plate, and the top-plate willbe confined between the bottom-plate 15 and the cover-plate. As a`result of this construction, the several members of the foot-piece willbe conveniently held in assembled relation while the spacers are beingtransposed, to effect adjustment of the side-lugs. A characteristic,4

resulting from the use of spacers between the ears on a plate of thefoot-piece and the side-lugs, is that the latter will be firmly clampedin their assigned position.

The invention exemplifies anV adjustable foot-piece for a. lever whichis composed essentially of sheet metal parts, and which can be readilyassembled, so that the foot-piece may be produced at a low cost. riheinvention also exemplifies an improved foot-piece, in which adjustmentof the side-lugs is effected by transposition of spacers which permit asingle bolt to securely clamp the sevvera-l parts together in theirassigned and connected relation. It also exemplifies foot-piece composedof sheet metal parts which will be held together in connected relationwhile the spacers are being transposed, and in which the spacers areclamped in place byy the boltwhich secures the sidelugs and one of theplates together.

The invention is not to be understood as restricted to the details setforth, since these may-be modified within the scope of the appendedclaims, without departingr from the spirit and scope of the invention.
